“…A possible solution for the problem with polishing difficult geometries, small bores and cavities is the usage of an electrolyte jet [4,5,17,18,19,20,21,22]. Ablyaz et al [17] and Novoselov et al [22] demonstrated the possibility of polishing an object with a complex geometry with a free electrolyte jet. In the works of Alekseev et al [20] and Cornelsen et al [4], the polishing of the inner surfaces of pipes was shown.…”
